Novel phenotypic and genotypic findings in X-linked retinoschisis.
OBJECTIVE To describe atypical phenotypes associated with the retinoschisis (X-linked, juvenile) 1 mutation (RS1). METHODS Seven patients with multiple fine white dots at the macula and reduced visual acuity were evaluated. Six patients underwent pattern and full-field electroretinography (ERG). On-off ERG, optical coherence tomography, and fundus autofluorescence imaging were performed in so...
متن کاملContrasting X-linked and autosomal diversity across 14 human populations.
Contrasting the genetic diversity of the human X chromosome (X) and autosomes has facilitated understanding historical differences between males and females and the influence of natural selection. Previous studies based on smaller data sets have left questions regarding how empirical patterns extend to additional populations and which forces can explain them. Here, we address these questions by...
متن کاملChromosome Number Variation in Iranian Populations of Acorus calamus
Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
متن کاملElectrophoretic Variation for X-chromosome-linked Phosphoglycerate
Electrophoretic variation €or X-chromosome-linked phosphoglycerate kinase (PGK-1) has been found as a polymorphism in feral mice in Denmark. Males from feral sampling or from a variety of genetic crosses have only a single-banded phenotype of the variant PGK-1A type or of the PGK-IB type commonly found among inbred mice. By contrast, three phenotypes were observed among females; two honozygous ...
متن کاملReduced X-linked diversity in derived populations of house mice.
Contrasting patterns of X-linked vs. autosomal diversity may be indicative of the mode of selection operating in natural populations. A number of observations have shown reduced X-linked (or Z-linked) diversity relative to autosomal diversity in various organisms, suggesting a large impact of genetic hitchhiking. However, the relative contribution of other forces such as population bottlenecks,...
